arduino-cli-debug-monitor

name	arduino-cli-debug-monitor
description	Debug session setup and serial communication workflows for supported boards. Use when requests involve `arduino-cli debug`, `debug check`, or `monitor`, including interpreter modes, debug metadata, and monitor port configuration.

Workflow

1. Check board and programmer debug support before session start.
2. Resolve and pass explicit debug artifacts or input directories.
3. Start debugger with the required interpreter mode.
4. Configure serial monitor settings before runtime observation.

Command Coverage

• arduino-cli debug
• arduino-cli debug check
• arduino-cli monitor

Defaults

• Use debug --info when metadata inspection is requested.
• Use monitor --describe before setting custom monitor configs.
• Add --timestamp in monitor mode for time-series debugging.

ICL Examples (Captured 2026-02-14)

1. Inspect monitor capabilities on the connected Nano serial port.

arduino-cli --config-dir /tmp/arduino_cli_suite_icl_data monitor --describe -p /dev/cu.usbserial-3120

Observed output listed settings for baudrate, bits, parity, rts, and stop_bits. 2. Stream live serial output from the sketch at 9600 baud.

arduino-cli --config-dir /tmp/arduino_cli_suite_icl_data monitor -p /dev/cu.usbserial-3120 --config baudrate=9600

Observed sample line from live output:

{"profile":"uno-dev","note":"icl example"}

3. Validate debugger support on AVR Nano target.

arduino-cli --config-dir /tmp/arduino_cli_suite_icl_data debug check -b arduino:avr:nano:cpu=atmega328old /Volumes/trent/Documents/Arduino/Arduino_CLI_Codex_Skills/tmp/icl_capture/project/icl_suite_demo_v2

Observed output: The given board/programmer configuration does NOT support debugging.
